Scheming Joan Colby (Ann Harding) tricks playboy John Fletcher (William Powell) into marrying her, and he's understandably miffed when he realizes he's been hoodwinked. It isn't long before Fletcher is straying from the nest in the company of his mistress Monica Page (Lillian Bond). A divorce is inevitable, but Joan, realizing the error of her ways, sets about to win Fletcher's love honestly -- and succeeds. Incidentally, director John Cromwell was the father of actor James Cromwell, an Oscar nominee for his performance in 1995's Babe.
